<%' Defining some constants to make my life easier! (Same as Sample 1)
' Begin Constant Definition
	' DB Configuration constants
	' Fake const so we can use the MapPath to make it relative.
	' After this, strictly used as if it were a Const.
	Dim DB_CONNECTIONSTRING

	'DB_CONNECTIONSTRING = "DRIVER={Microsoft Access Driver (*.mdb)};" _

	' We don't use these, but we could if we neeeded to.
	'Const DB_USERNAME = "username"
	'Const DB_PASSWORD = "password"
	'Now we override the above settings to use our SQL server.
	'Delete the following line to use the sample Access DB.

		& "Connect Timeout=15;Network Library=dbmssocn;"
	' ADODB Constants
	' You can find these in the adovbs.inc file
	' Do a search for it and it should turn up somewhere on the server
	' If you can't find it you can download our copy from here:
	'     http://www.asp101.com/samples/download/adovbs.inc
	' It may not be the most recent copy so use it at your own risk.

'  3. Find the record to delete
'  4. Delete It!
'  5. Update the table
'  6. Close the Recordset

	' Get the Id of the record to delete

	' We're looking to delete the only record from the current recordset.
	' The first one is the one to delete.
	' Note: If the data was a little more important (or of any value at all
	' to us!), we'd probably check some other criteria or at least check to see
	' if it's the oldest record in the recordset.  Since it's not and we really
	' don't care, here goes!
'Step 4:
	'Make sure we actually have a record to delete.

		' You can also delete groups of records which satisfy the filter
		' property setting if you're doing this in batch mode.  For this
		' situation we're just killing the one record so we don't bother.
	End If
'Step 5:
	' We don't need to do the update unless we batch it like mentioned above!
	'objRecordset.UpdateBatch
	' Show a message saying we deleted a record
	If iRecordToDelete <> 0 Then
		Response.Write "Record id " & iRecordToDelete & " deleted!"
